【Ten Years of Rapid Development in Chemical Engineering Equipment】2748-2025: Bohai Equipment Achieves Domestic Production of Key Components for High-Power Flue Gas Turbines

Thread Content

Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. Your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Progress in Chemical Engineering Equipment】A continuously updated summary post is available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On October 10, reporters learned that after nearly a decade of continuous efforts, Bohai Equipment Petrochemical Equipment Company has successfully achieved domestic production of three key components for ultra-high-power flue gas turbines: the large rotors, bearings, and large blade bars. The performance standards of these components meet or exceed the required levels, marking a significant breakthrough for China in the field of self-sufficiency in high-end energy and chemical engineering equipment. Flue gas turbines are the core components of energy recovery systems in industries such as petrochemicals and coal chemicals, playing an irreplaceable role in improving the efficiency of comprehensive energy utilization and ensuring the safe and economic operation of these facilities. However, ultra-high power flue gas turbines are constantly exposed to extreme operating conditions such as high temperatures, high pressures, and severe wear, which imposes extremely strict requirements on design precision, manufacturing processes, and material properties. Their key components rely heavily on foreign supplies, posing a bottleneck that hinders the independent development of related industries in our country. In the face of technical barriers, the company concentrated its resources on carrying out targeted efforts to overcome these challenges. Through continuous research and development as well as experimental optimizations, it achieved substantial breakthroughs in the design and manufacturing technologies for key components such as large disks for ultra-high power gas turbines, high-performance bearings, and large-sized blade bars, reaching a technical level that is fully capable of replacing imported products. The domestically developed large-scale turbine that has been successfully developed in this project will first be put into industrial use at Guangxi Petrochemical Company, and then gradually introduced to more user organizations, with the ultimate goal of achieving full domestic substitution for ultra-high-power flue gas turbines. Bohai Equipment has made breakthroughs in the localization of gas turbine technology; advancements have been achieved in three key components. After a decade of efforts, Bohai Equipment has overcome technical challenges such as the overall forging of large rotors, the development of high-performance bearings capable of withstanding extreme conditions, and the precise processing of large-sized blade blanks. The key performance indicators have reached international leading levels. Verification under extreme conditions: The components must operate continuously at high temperatures of 720°C, high pressures of 10 MPa, and in environments with high wear. Domestic products have passed more than 2,000 hours of industrial testing, demonstrating superior reliability compared to imported products. Domestic application and industrial promotion: The first pilot installation was carried out in October 2025 at a catalytic cracking unit in Guangxi Petrochemical; it is expected to generate 320 million kWh of electricity annually, thereby reducing equipment procurement costs by 40%. Timeline for replacing imports: It is planned to complete the renovation of 12 flue gas turbines within CNPC’s system by 2026, with full import substitution across the industry to be achieved by 2028. Supply agreements have already been signed with Zhenhai Refining & Chemical and Hainan Refining & Chemical. Strategic significance of localization: Overcoming critical bottlenecks – Previously, China was entirely dependent on imports for the core components of gas turbines with a capacity of over 10,000 kW; with localization, the procurement cycle was reduced from 18 months to 6 months, thereby avoiding risks associated with international supply chains. Economic benefit analysis: Based on the current market size, full replacement would result in annual savings of over 800 million dollars in foreign exchange expenses, while also driving an increase in the output value of related industries such as superalloy materials and precision machining by 12 billion yuan.
